This page discusses the Peak Current Mode Control of a Buck Converter and explores how its operation can be automated with Altair HyperStudy. If you have not experimented with HyperStudy before, you should read this article as a first step. What is PCMC and what are its advantages compared to other control techniques? Peak…
In the field of mechanical engineering, different equipment is designed to handle bulk materials. Discrete element method (DEM) and Finite element method (FEM) are two numerical methods available for researchers and engineers to develop new products and address complex engineering problems. These two methods have their…
Suppose you missed the ATCxAEC presentation or want to revisit it. In that case, you can find the recording here. In this workshop, we showcase how Altair's Concrete solutions help you easily design high-rise buildings' reinforced concrete elements, from an existing model, code-checking, and getting utilization ratios for…
S-FRAME suite v2025.1 has been released, and with this, some additions and enhancements aimed at improving the everyday workflow for its users. In the next paragraphs, you can find the main features. Concrete Design As part of the advances on including GFRP design within the S-FRAME suite, S-CONCRETE now supports…

Join us for an introduction to analysis and design of a hybrid timber-and-steel structure in a step-by-step tutorial. We’ll review geometry…
Presentation by Matthew Sauer, Manager GTT at Altair as part of the ATCx AEC 2025 conference.Additionally, Altair’s SimSolid software helped optimize bolted connections in a modular pump box, enhancing its design and structural integrity. Join us as we introduce the mesh-free simulation of SimSolid in a step-by-step…
Numerical EM simulation is an established approach to optimize and validate designs for reflector antennas. For electrically large structures, however, memory requirements and runtimes can become quite extensive. In this paper we show recent improvements of MLFMM (Multi-Level Fast Multipole Method) implementation in Altair…
Inverter's Average Model: A Streamlined Approach The average model of an inverter represents a distinct approach compared to ideal or thermal models. This model is designed to expedite simulations by omitting the detailed switching phenomena. By focusing on the overall behavior rather than individual switching events, the…
Problem Statement The increment of renewable energy sources has introduced issues that concern the integration of them in the electric grid without influencing its stability. This new challenge on the way to electrification has created a need for capturing transient phenomena in a short - time simulation. The further…
Computational time has always been one of the most important aspects of DEM Modelling. Initially, it could be assumed that having an accurate and realistic material model through material calibration is the main target. If you want to learn about material calibration, read this post:…
